2013-10-16ath10k: fix ath10k_bss_assoc() to not sleep in atomic contextKalle Valo1-19/+37
ath10k_bss_assoc() was calling ath10k_peer_assoc(), which can sleep, under atomic rcu_read_lock() and causing scheduing while atomic errors. Workaround that by delaying the call to ath10k_wmi_peer_assoc(). Signed-off-by: Kalle Valo <[email protected]>
2013-10-16ath10k: remove unnecessary checksMichal Kazior1-21/+0
mac80211 interface iteration functions that were used originally iterated over interfaces that weren't re-added to the driver during recovery. Since internal vif list is now used it's safe to remove the safe-guard as internal vif list is based on add/remove_interface function which guarantees that vdev is created in FW before it is iterated over.

2013-10-16ath10k: fix scheduling while atomic config bugMichal Kazior1-84/+62
Recent HTC/WMI changes introduced the bug. ath10k was using _atomic iteration function with sleepable functions. mac80211 provides another iteration function but it cannot be safely called in hw_config() callback due to local->iflist_mtx being possibly acquired already. The patch uses internal vif list for iteration purposes and removes/refactors no longer necessary _iter functions.

2013-10-16ath10k: fix add_interface failure handlingMichal Kazior1-13/+40

2013-10-16ath10k: use workqueue to set WEP TX keyMichal Kazior2-18/+39
Recent WMI/HTC changes made it possible for WMI commands to sleep (if there's not enough HTC TX credits to submit a command). TX path is in an atomic context so calling WMI commands in it is wrong. This simply moves WEP key index update to a worker and fixes the 'scheduling while atomic' bug. This still leaves multiple WEP key handling laggy, i.e. some frames may be TXed with an old/different key (although recipient should still be able to RX them). kvalo: changed the title Signed-off-by: Michal Kazior <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2013-10-11net: smc91x: dont't use SMC_outw for fixing up halfword-aligned dataWill Deacon1-4/+2
SMC_outw invokes an endian-aware I/O accessor, which may change the data endianness before writing to the device. This is not suitable for data transfers where the memory buffer is simply a string of bytes that does not require any byte-swapping. This patches fixes the smc91x SMC_PUSH_DATA macro so that it uses the string I/O accessor for outputting the leading or trailing halfwords on halfword-aligned buffers.

In certain corner cases in the firmware implementation, powersave transitions can cause the firmware to miss the fact that commands were added to the queue/FIFO and thus never processes them. Since the commands really are in the queue, try to poke the firmware in such cases (by grabbing NIC access, which wakes up the NIC) so it notices the new command and processes it.
